At first I expected the advent of mass vaccination to end the pandemic, because it only had to drop R by a factor of two or so to drop below the critical percolation threshold, so even a vaccine providing 50% sterilizing immunity would be good enough, and the mRNA vaccines turned out to be even more effective than expected. I turned out to be spectacularly wrong about that; as you may or may not be aware, the pandemic did not end a year ago. It turned out that, unlike vaccines like the smallpox vaccine, the covid vaccines did not provide much sterilizing immunity.

Moreover, the virus has become endemic in a number of zoonotic reservoirs, including deer, feral cats, and some mustelids, and vaccinating or exterminating those populations is not realistic in the next few decades. This is not currently a significant source of human outbreaks as far as I can tell, but after the humans reach herd immunity, it will be the only one.

Consequently, the cost-benefit tradeoff for covid vaccinations with the currently available vaccines needs to be evaluated with respect to the benefit to the person being vaccinated. I'm glad I'm vaccinated: as an obese 45-year-old man, my risk of death from covid might approach 1%, which is enormously higher than any plausible risks from any of the vaccines I'm familiar with. But that tradeoff is not the same for everyone, and there are populations where the rate of death or permanent harm from a vaccine, though still extremely low, is likely higher than the rate of death or permanent harm from covid itself.

The situation would be different if, for example, vaccinating schoolchildren prevented them from infecting and inadvertently killing their grandparents. But it doesn't. So the fact that the existing vaccinations clearly fail to control the spread is extremely relevant to the cost-benefit tradeoff, in particular because it means that there's no valid public-interest argument for requiring people to get vaccinated. Since both the cost and the benefit flow to them individually, they should be able to make the decision individually, except in cases such as small children and comatose patients.

This is an argument that deserves rational consideration, not dismissal with mindkiller phrases like "vapors" and "anti-vax". That's the sort of argument, or rather non-argument, that "deserves to lose".
